Apache POI 是用Java编写的免费开源的跨平台的 Java API，Apache POI提供API给Java程式对Microsoft Office格式档案读和写的功能。POI为“Poor Obfuscation Implementation”的首字母缩写，意为“简洁版的模糊实现”。
POI生成excel是比较常用的技术之一，但是用来生成word相对来说比较少，今天演示一下利用POI生成word文档的整个流程,，当然方法有很多种，这是我感觉比较方便的一种。
需要实现的功能：
在文档中动态生成章节标题、文本段落、表格标题、表格、统计图等等。给每个章节编号删除没有替换的占位符
总体思路：
这种方法的本质其实是动态替换，动态替换的意思是在模板中写入很多某种特定格式的占位符(关键词)以及图的样例，如果前端需要生成这个章节的内容，那么，把这个关键词传到后端，再在模板中寻找关键词，有则替换成具体内容，无则不替换。最后把没有替换掉的占位符删除，从而达到动态替换的效果。
具体实现过程如下：
创建word模板.文档中包含若干个章节，章节中包含章节标题、文本段落、表格标题、表格、统计图的占位符。占位符的内容依据自己的实际情况而定。加载模板，判断该章节是否存在，如果存在就替换具体数据。本示例数据都是模拟的，实际情况应该从数据库中查出。再次遍历替换后的word文档，把没有替换掉的占位符删除。
示例
1. 创建模板
如下图所示:
